thanks for the diagram. I'm a first time BMW owner to be. For the 328i, does the element "11427640862" have to be removed by unscrewing the cover? (part 11427525334)

Is it the element that needs to be replaced?

On most cars, I'm used to seeing just one big cannister. You remove the entire canister & replace it with a new one and throw away the old oil filter cannister. I've never had to disassemble the cannister itself to change the filter.
